-scripted way: the story is written in advance and the requirement is that the player advances it.

-non scripted way: the game feeds the player with narrative elements that the player strings together to elaborate the story.

Players for most of them prefer the scripted way.

The scripted way is the least adapted to video games and comes with limitations.
It is mostly navigating through a flow chart of various narrative branching.

Bioware's experience showed that it can not be sustain in the mid term (from one episode to another) as the project collapses under the developpment costs to follow up all the branching (if then else)

Instead of taking that into account, that scripted stories, the choice and consequences stuff (another so called hallmark to socalled RPGs) is not sustainable, this author now wants to step up the game and would want an elaborating narrative AI.

The elaborating narrative AI, once fed with the general directions of a story, will developp by itself the story, according to the inputs of the player.and while maintaining the general direction of a story.

Quite a programm.

Days when RPGs were about role playing are long, long gone. Now players want a parent telling them bed time stories and adapting the story according to the reaction of the child.
